Complicated issue and error msg

Two things here:

Yes, I already understand about operating syndicated accounts in LJ using feeds to update LJ with a site's latest content , but here is the issue: Ok, what if an attorney I am helping out with live journal wants to take all of his existing posts on his existing website which is Personal Injury Attorney Augusta .com and syndicate these into individual posts automatically on LJ without having to do this manually? Here is the other issue, say he has 10 or 14 different post categories on his main website and he will posting to each category once a month. Any suggestions on how to organize this data on LJ? The post categories are related yet so diverse it wouldn't make sense for them to necessarily be thrown together in LJ.

The next issue kept coming up when installing Live Journal on the server. I have never gotten this message before.
